Possibly, but I don't see how...
If I use a different source, i dont get the noise
ie, if i connect my ipod or laptop directly to the amplifier, I dont get the crackling noise.
BUT, what you suggested is one of the things i havent tried yet. Im going to run a new line to the speaker...

Just moved the ground from the factory ground point on drivers side, to passenger seat rail.
Also ran new wire to left speaker, and disconnected right speaker.
STill getting the noise.....
I think this one has me beat. :/

Connected the HU to the battery in my other car. It's making clean power on its own.
There must be something IN the power of the car causing the issue... I just cant imagine what...
The whole issue started immediately after I bypassed my EQ to test the sound without it.
There just isn't any way to fix this.
The only thing that makes sense, is that there is a 'signal' in the power grid, which the heavily shielded RCAs pick up on their own, which the HU picks up on, but for some reason the amp DOES NOT..... Bizzarre.

Update:
If i pull the RCA from the head unit, and touch the middle conductor to my wedding ring, it makes the EXACT same noise.
Also, I plugged in the WRONG rca cable, and still got music from my speakers (though faintly, this RCA was not plugged into the amp.) It was within a foot of the cable that was.
Furthermore,
I only have the LEFT speaker connected. If i connect ONLY the RIGHT rca to the RIGHT output of HU and RIGHt input of amp, I STILL get music out of the Left speaker, at about 15% volume.

PV, I touched the outer shell of the RCAs to the head unit, and the noise is gone. (And the stereo sounds a bunch better, too)
So the shield is ungrounded, and I now have a pair of antennaes...
I guess I could wire a ground line into the RCA and connect to the HU chassis, but does that really solve the problem?
Doesn't this indicate a more serious problem? Or can I just ground the shields and call it done?
Thanks so far bud.

ok if im reading this correctly, you grounded the ring and the problem went away.
This is a notorious problem with pioneer radios basically anytime you dick with rca's with a pioneer radio you have to unhook the battery, i will explain this best i can. Basically when you unplugged or plugged something in something for a split second tried to ground out through the rca frying the bridge inside of the headunit. Basically when you went from the ring of the rca to the the chasis of the headunit you were remaking this connection that fried out. If the radio is new i would send it back and ask for a new one otherwise yes running a wire from the outerring on the rca to the chasis of the radio is a perfectly find way to fix this its done everyday.

Best buy wont exchange it, so I'll just do the workaround.
I wonder if this is why I heard that 'weirdness' in the left tweeter... seemed like a different song in the background
Looks like the Dyn budget is safe.... now do I want new Dynaudio speakers... Or new EQ. )
